| | |
| | | ```sh |
| | | cd egs/aishell/paraformer |
| | | ``` |
| | | |
| | | Then you can directly start the recipe as follows: |
| | | ```sh |
| | | conda activate funasr |
| | | . ./run.sh |
| | | ``` |
| | | The training log files are saved in `exp/*_train_*/log/train.log.*`, which can be viewed using the following command: |
| | | |
| | | The training log files are saved in `${exp_dir}/exp/${model_dir}/log/train.log.*`, which can be viewed using the following command: |
| | | ```sh |
| | | vim exp/*_train_*/log/train.log.0 |
| | | ``` |
| | | |
| | | Users can observe the training loss, prediction accuracy and other training information, like follows: |
| | | ```text |
| | | ... 1epoch:train:751-800batch:800num_updates: ... loss_ctc=106.703, loss_att=86.877, acc=0.029, loss_pre=1.552 ... |
| | | ... 1epoch:train:801-850batch:850num_updates: ... loss_ctc=107.890, loss_att=87.832, acc=0.029, loss_pre=1.702 ... |
| | | ``` |
| | | |
| | | Also, users can use tensorboard to observe these training information by the following command: |
| | | ```sh |
| | | tensorboard --logdir ${exp_dir}/exp/${model_dir}/tensorboard/train |
| | | ``` |
| | | |
| | | At the end of each epoch, the evaluation metrics are calculated on the validation set, like follows: |
| | | ```text |
| | | ... [valid] loss_ctc=99.914, cer_ctc=1.000, loss_att=80.512, acc=0.029, cer=0.971, wer=1.000, loss_pre=1.952, loss=88.285 ... |
| | | ``` |
| | | |
| | | The inference results are saved in `exp/*_train_*/decode_asr_*/$dset`. The main two files are `text.cer` and `text.cer.txt`. `text.cer` saves the comparison between the recognized text and the reference text, like follows: |
| | | The inference results are saved in `${exp_dir}/exp/${model_dir}/decode_asr_*/$dset`. The main two files are `text.cer` and `text.cer.txt`. `text.cer` saves the comparison between the recognized text and the reference text, like follows: |
| | | ```text |
| | | ... |
| | | BAC009S0764W0213(nwords=11,cor=11,ins=0,del=0,sub=0) corr=100.00%,cer=0.00% |
| | |
| | | * Training Steps |
| | | |
| | | We support two parameters to specify the training steps, namely `max_epoch` and `max_update`. `max_epoch` indicates the total training epochs while `max_update` indicates the total training steps. If these two parameters are specified at the same time, once the training reaches any one of these two parameters, the training will be stopped. |
| | | |
| | | * Tensorboard |
| | | |
| | | Users can use tensorboard to observe the loss, learning rate, etc. Please run the following command: |
| | | ``` |
| | | tensorboard --logdir ${exp_dir}/exp/${model_dir}/tensorboard/train |
| | | ``` |
| | | |
| | | ### Stage 5: Decoding |
| | | This stage generates the recognition results and calculates the `CER` to verify the performance of the trained model. |
